Ive transitioned from vegetarian (3 months) to vegan (2 months now) but i havent take any supplement or b12 so far, i live in mexico so most of the supplements i find in internet are not available here si if you could guide me with the name of the vitamins id need with amounts and intake frequency id be appreciated.

A lot of plant based "milks" are fortified with b12, and vegan breakfast cereals are fortified with b12 a lot of times. Eat good food, and you really will not need to take supplements. If you can find a decent vegan multivitamin online that you can get in your country, that would fill in the gaps that you are missing.

Bodybuilding.com says they ship to Mexico, and they have a few different kinds of vegan vitamins on there. Might want to email them to double check on the shipping etc..but that might be a good route to go! Good luck!

B12 is the only supplement (fortification is also a type supplement) vegans in industrialized living conditions need, given a generally balanced diet. I don't know what the above poster means by eating "good food," but I ate good vegan food for years and still ended up with health problems that were immediately eliminated once I started taking B12. Don't skip it.
